the d**n thing has to go slow (1 to 1.5 mph with a 20' head in 60 bus. wheat) in wheat because it get's plugged up with the staw, is there settings I should try that will help this? thought I tryed them all but have forgot. and are there block off plates I can put in the concaves?????????

They are called awning plates, 4 plates, 2 per rotor, fit in the front section of the concave. For hard thrashing wheat or other crops that are difficult to get out of the head,these are a great help.

Are the concaves plugging, or are the rotors slugging and not carrying material to the rear quickly enough?

it is breaking up the straw really fine and the straw will plug the hole on the concaves and the grian go out the back

It may be that your concaves are rounded over -- if the concave crossbars can't retard the incoming material properly for thresh, you have to pull them up close to the rotor. This in turn causes the requirement for higher rotor speeds in order to feed the machine, thinning out the load. The MOG is held on the concaves longer, as well, causing it to break up into smaller components which drop thru the concave openings too quickly and you'll also likely see some whitecapping and hairpinning in the concave wire openings. Worn rotor bars can cause a small fraction of this problem, but actually have very little to do with it.
If concaves are worn out, it may follow that the augers on the fronts of the rotors are also worn, along with the auger extensions. If the augers can't feed properly the MOG will be stationary and the augers will beat it until an adequate load builds up allowing the MOG to be fed rearward. This also will require faster rotor speeds in order to pull from the feederhouse --faster rotor speeds will tear up MOG more quickly.
A couple more questions -- are your rear separator grates plugging also? Do you have the universal concaves (1/8" wires in the top row and 1/4" wires in the bottom row) installed, and if you're using these, do you have the small wires installed?
We've found that usable life on most original installation TR series concaves is about 1400 to
2000 hours and that rotors need to be rebuilt at around 2300 to 2600 hours. Ther'es more to this, but these are usually the first things to check. Hope it all makes sense.
